I see.  Powers of two allocated out of page quanta really bound this in
practice--McKusick's experience has been born out in my experience, both in
actual UNIX kernels (HP-UX, PTX) as well as in ForthOS.  Of course, the
resource efficiency of Forth (and ForthOS) intersecting with modern bounty of
RAM means it's easy to have "plenty".
